Abstract

Wireless communication methods, a device and a storage medium are provided. A method includes: a station transmits a first message to an access point, the first message carrying a field indicating a highest modulation and coding scheme (MCS).

1 . A method for wireless communication, comprising:
 transmitting, by a station (STA), a first message to an access point (AP), the first message carrying a field indicating a highest modulation and coding scheme (MCS).   
     
     
         2 . The method of  claim 1 , wherein the first message is used for the STA to change supported maximum MCS. 
     
     
         3 . The method of  claim 1 , further comprising:
 receiving, by the STA from the AP, a first physical layer protocol data unit (PPDU) for an extended range,   wherein the STA is a 20 MHz-only device.   
     
     
         4 . The method of  claim 3 , wherein a preamble of the first PPDU comprises a second field for indicating that a PPDU in which the second field is located is the first PPDU. 
     
     
         5 . The method of  claim 1 , wherein different MCSs are used by the STA for different streams when performing PPDU transmission. 
     
     
         6 . The method of  claim 1 , wherein the field is a high throughput (HT) control field, and the highest MCS is indicated by a first field in a high efficiency (HE) variant of an A-control field in the HT control field. 
     
     
         7 . The method of  claim 6 , wherein the first field is an extremely high throughput (EHT) operating mode (OM) control subfield or a defined control information subfield. 
     
     
         8 . The method of  claim 7 , wherein the highest MCS is indicated by a reserved field in the EHT OM control subfield. 
     
     
         9 . An access point (AP), comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program to cause the AP to:
 receive a first message from a station (STA), the first message carrying a field indicating a highest modulation and coding scheme (MCS).   
     
     
         10 . The AP of  claim 9 , wherein the processor is configured to call and run the computer program to cause the AP to transmit a first physical layer protocol data unit (PPDU) for an extended range to the STA,
 wherein the STA is a 20 MHz-only device.   
     
     
         11 . The AP of  claim 10 , wherein a preamble of the first PPDU comprises a second field for indicating that a PPDU in which the second field is located is the first PPDU. 
     
     
         12 . The AP of  claim 9 , wherein different MCSs are used by the AP for different streams when performing PPDU transmission. 
     
     
         13 . The AP of  claim 9 , wherein the field is a high throughput (HT) control field, and the highest MCS is indicated by a first field in a high efficiency (HE) variant of an A-control field in the HT control field. 
     
     
         14 . The AP of  claim 11 , wherein the first field is an extremely high throughput (EHT) operating mode (OM) control subfield or a defined control information subfield. 
     
     
         15 . The AP of  claim 14 , wherein the highest MCS is indicated by a reserved field in the EHT OM control subfield. 
     
     
         16 . A station (STA), comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program to cause the STA to:
 transmit a first message to an access point (AP), the first message carrying a field indicating a highest modulation and coding scheme (MCS).   
     
     
         17 . The STA of  claim 16 , wherein the first message is used for the STA to change supported maximum MCS. 
     
     
         18 . The STA of  claim 16 , wherein the processor is configured to call and run the computer program to cause the STA to receive a first physical layer protocol data unit (PPDU) for an extended range from the AP,
 wherein the STA is a 20 MHz-only device.   
     
     
         19 . The STA of  claim 18 , wherein a preamble of the first PPDU comprises a second field for indicating that a PPDU in which the second field is located is the first PPDU. 
     
     
         20 . The STA of  claim 16 , wherein different MCSs are used by the STA for different streams when performing PPDU transmission.
